Hydromodule Test Stand


A Tier 1 manufacturer of hydraulic pumps and motors for construction and agriculture equipment builders selected our company to build a machine to test pumps. The challenges proved to be keeping the oil contained in the machine during flushing and getting the customer-supplied control valves to work properly. The goal was a total test cycle time of 10 minutes per unit.


This system automatically flushed and tested finished Hydromodule assemblies and recorded the test data. Manual operations included loading and unloading the station with the aid of a hoist and inserting four plugs and one orifice screw.

The Hydromodule Test Stand incorporated technology that the customer had not utilized previously. These aspects included a 200 hp drive motor and hydraulic ‘load/brake’ motor with belt drives, pneumatic safety clutches and torque transducers, a quick-load and quick-connect design for the 350-pound pump units, a sliding-cover test bed area to accommodate internal and external cleaning flushes, new Controls/Testing software using CVI LabView with National Instruments equipment, and particle count evaluation of the hydraulic fluid to monitor unit assembly cleanliness. All of this was built onto a large, single-unit machine base.

outcomes and benefits

All the challenges and customer goals were met, including hydraulic oil containment, use of customer-supplied valves, and a 10-minute cycle time. The customer is extremely pleased with the machine. The early successes resulted in our company getting a second similar project while this one was underway.
